Seatrium Limited has finished and delivered a next-generation Wind Turbine Installation Vessel to Maersk Offshore Wind. The formal handover took place on February 26, 2026. The newbuild next-gen WTIV shows that the Seatrium is committed to advanced installation skills that can adapt to the changing needs of big offshore wind projects.
Seatrium has designed the next-gen WTIV to handle some of the biggest offshore wind turbines in use today. It brings improved installation capacity to the market. The primary crane on the ship weighs 1,900 tons and has a hook height of 180 meters. The vessel is designed to lift and install turbines with a capacity of 15 MW or more.
The next-gen WTIV will set out for its first operation from the Empire Wind project off the coast of New York in March 2026. There, it will help with the supply of clean energy to 500,000 homes.
The construction plan included various complex and difficult steps supervised by top international classification societies. It has a stabilizing system that keeps feeder vessels in place during component transfers, even when the sea is rough. This setup enables for continuous offshore activities by extending the operational weather window. This makes operations more efficient and cuts down on the time and money needed for the installation as a whole. The feeder-based approach meets the requirements of the US Jones Act and can be used in many different areas.
Seatrium kept a strong focus on safety performance during the build, and there were no Lost Time Injuries (LTIs) during the work. This next-gen WTIV adds to Seatrium’s larger offshore wind portfolio, which includes floating foundations, offshore substations, zero-emission vessels, and specialized installation assets. With each project, the Group’s position as a vital player in aiding the fulfillment of net-zero goals grows even stronger.
